CORNER FOR BUILDINGS.

Specification of Letters Patent.

Patented Aug. 19, 1919.

` Application led May 23, 1918.` Serial No. 236,160.

To all whom it may concern.'

Be it known that I, JOHN K.. SHAW, a

citizen of the United States, residing at' Minneapolis, in the county ofHennepin and State of Minnesota, have invented certain new and usefulImprovements in Corners for Buildings; and I do hereby declare thefollowing to be a full., clear, and exact `description of the invention,such as will enable others skilled in the art to which.. it

` appertains to make and use the same.

- construction and combinations of parts more fully hereinafterdisclosed and particularly v pointed out in thc claim.

Referring to the accompanying drawings forming a part of thisspecification in which like numerals designate like parts in all the aviews: p

Figure 1 is -an elevational view of the corner of a house made inaccordance with this invention;

Fig. 2 is a cross sectional view on the line l ing material such as theboards shown, and.

5 Yand 6 a pair of boards made of insulite or paper board materialsecured to the sides 4and 5 respectively.

In Vorder that the precise invention may be the more clearly understoodit is said:

The paper board material constituting insulite differs radically fromordinary paper boardv material in that it contains some fibers 7 whichare as large as slivcrs, they being sometimes 1/ 8 inch wide and 1/2,inch

- long. It also containsother fibers 8 of a4 string like nature, theybeing sometimes 1/32 or 1/64 of an inch in diameter and 1 or 2 incheslong. In addition to these abnomally coarse fibers 7 and 8, this saidmaterial contains` a third class of hairlike fibers whose diameter maynot be over say 1/100 to 1/200 of an inch and whichare say from 1/2 inchto 2 inches long; and

mixed with these hair like `fibers is a fourth class of fibers which areidentical with those employed in making paper. wide variations in thecoarseness of the ibersgoing to make up the board causes These very' the,insulite to be unusually porous, to-

have an unusually low specific gravity of say .3 or .2 to be anexceptionally high heat insulating material, but to be more or lessfragile at the edges and therefore easily broken ,when it comes tofastening said edges. Saidedges accordingly rapidly deteriorate whenexposed to the weather, un-

the upper boards overlapping the lower, and4 I provide the Wedge shapedpieces 10 and 11 toA fill the spaces between the successive boards andthe walls 4 and 5. Outside the meeting end edges 20 and 21 of a pair ofboards, I provide the vertically disposed strips 25 and 26 joined as at27,` and on the inside of these strips I provide inclined recesses 28having the bottom walls 29, against which fit the side edges 30 of theinsulite boards. n ingly conceal and protect the extreme end portions ofsaid boards. In other words, these said recesses 28 in each of thestrips 25 and 26 form pockets which are inclined to the vertical, andwhich are closed on one side by the wedge members `11 while the bottomsAof said pockets are closed by the walls 29, and'one end of said pocketsis closed by the material of said strips 25 and 26, themselves. Thesepockets are therefore 'of the same size and dimensions as are the endsof the insulite strips 5 and 6, so that said insulitc strips snugly .fitinto said pockets and are therefore effectually protected againstdeterioration from the weather. All the parts aro s. .tably nailed, orotherwise These recesses 28 accord-` sure may be lined with insuliteboards 10 terial 40. In order to laccommodate sai` or panels 7', andsaid last named boards covered with plaster or other sealing ma`4 boards7 and sealing material, the en pieces l and 3 may be offset as shown toform a rectangular recess 41.

What I claim is: l In a house the combination of a .corner structure; aside Wall structure j oining said;- v1corner structure; a second sideWall struc- 1 ture joining said corner structure and makmisano ing/- anangle with said rst named side .wall structure; a set of overlappingporousl boards of insulite material having fragile edges overlying saidli'rst named side Wall structure; a secondzset of porous overlappingnsulite boards having fragile -edges overlying said second side- Wall pstructure;- a pair of vertically disposed. strips provided with recessesof the 'shape and dimensions of the end portions of said boards and intowhich said-end portions snugly fit; Wed e members. located between saidside Wal structures and said boards, and serving to close one sideof'said recesses and canse the -ends of said boards to .be held `rmly inplace,'substantially as-described.
